State whether the following statements is true/false regarding DNA replication.

1. Proteins bind to both origin sites and termination sites on DNA during DNA replication.

2. In the Sanger method for DNA sequencing, the gels are read from bottom to top, since the smallest fragments travel farthest in the sequencing gel.

3. DNA polymerase I which is inhibited by dideoxynucleoside triphosphates is used in the Sanger method for DNA sequencing.

4. Sanger DNA sequencing requires inhibition of DNA polymerization by a specific dideoxynucleoside every time it is copied in the replication process.

5. The Klenow fragment can be used for DNA sequencing if proteins such as SSB protein are added.
